Lithium Silicate Liquid
Lithium silicates are aqueous solutions resulting from combinations of lithium oxide (Li₂O) and colloidal silica (SiO₂) in varying proportions. These liquids combine valuable characteristics of soluble silicates and colloidal silica. For example, they offer alkalinity levels that are higher than colloidal silica but much lower than sodium and potassium silicates. In addition, they possess very good film-forming and binding properties.
We have expanded our product portfolio, which now includes grades with molar ratios of SiO₂/Li₂O ranging from 2.95 to 7.50.
Properties & Advantages
- Lithium silicates are high-ratio, low-viscosity solutions.
-
Compared to sodium and potassium silicates:
o they are less alkaline
o they are less soluble once they are dried
o they exhibit fewer desalting effects - They have excellent film-forming and binding properties.
- The binding and refractory properties of sodium and potassium silicates can be improved by mixing them with lithium silicate.
